Blood vessels are crucial in the human body, providing essential nutrients to all tissues while facilitating waste removal. As the incidence of cardiovascular disease rises, the demand for efficient treatments increases concurrently. Currently, the predominant interventions for cardiovascular disease are autografts and allografts. Although effective, they present limitations including high costs and inconsistent success rates. Recently, synthetic vascular grafts, made from artificial materials, have emerged as promising alternatives to traditional methods. Among these materials, bacterial cellulose hydrogel exhibits significant potential for tissue engineering applications, particularly in developing nanoscale platforms that regulate cell behavior and promote tissue regeneration, attributed to its notable physicochemical and biocompatible properties. This study reviews recent progress in fabricating engineered vascular grafts using bacterial nanocellulose, demonstrating the efficacy of bacterial cellulose hydrogel as a biomaterial for synthetic vascular grafts, specifically for stimulating angiogenesis and neovascularization.
血管在人体中至关重要,为所有组织提供必需的营养物质,同时促进废物排出。随着心血管疾病发病率的上升,对有效治疗方法的需求也随之增加。目前,心血管疾病的主要干预手段是自体移植和异体移植。尽管有效,但它们存在一些局限性,包括成本高和成功率不一致。最近,由人工材料制成的合成血管移植物已成为传统方法的有前途的替代方案。在这些材料中,细菌纤维素水凝胶在组织工程应用中具有巨大潜力,特别是在开发调节细胞行为和促进组织再生的纳米级平台方面,这归因于其显著的物理化学和生物相容性特性。本研究综述了使用细菌纳米纤维素制造工程血管移植物的最新进展,证明了细菌纤维素水凝胶作为合成血管移植物生物材料的有效性,特别是在刺激血管生成和新血管形成方面。
